Can a dash cam record audio?

[SanAubree]

Dash cams can record audio by default. The functions of a dash cam: Dash cams usually have an external camera, with the main function of recording the driving conditions outside the vehicle. However, they can also record sounds inside the car, but cannot capture images of the interior. Wiring methods for dash cams: Generally, dash cams have two wiring methods: connecting to the cigarette lighter or to the fuse box. The advantage of connecting to the cigarette lighter is the simplicity of wiring, but it may affect aesthetics and occupies a cigarette lighter port. Normally, the cigarette lighter is connected to the ACC, meaning it only has power when the ignition is on. Therefore, dash cams connected to the cigarette lighter cannot achieve 24-hour parking surveillance. Connecting to the fuse box allows direct connection to the car battery, enabling 24-hour parking monitoring. However, the downside of connecting to the fuse box is that it is more complicated and usually requires professional installation, but this method hides the wires, making it more aesthetically pleasing.
